[debian-knoppix] problem with config files in persistant home directory

[Orson Jones <orsonj@bookstore.usu.edu>]

Short story: 
 Can you make it not unmount my home directory when I have my config files 
saved in my home directory? 
 
 Long story: 
 I made a persistant home directory using the entire partition of my USB 
memory stick. 
 USB disk is now one partition formatted as ext2. 
 (I now have to boot with option home=/dev/sd[a..z]1 rather than home=scan. 
 Suggestion: if it finds an empty knoppix.img file on a partition, and the 
partition is ext2, then mount that partition as /home/knoppix or perhaps name 
the partition Knoppix and look for that.) 
 
 Back to the real problem. 
 I later saved the configuration on the same USB stick. 
 (booted with options: "knoppix home=/dev/sdb1 myconfig=scan") 
 (I added a line to the default knoppix.sh script to debug a bit.) 
 
 knoppix@ttyp0[knoppix]$ cat /mnt/sdb1/knoppix.sh 
 #!/bin/sh 
 [ "`id -u`" = "0" ] || { echo "You need root privileges to modify the 
system!" >&2 ; exit 1; } 
 [ -d "$1" ] && CONFIGS="$1/configs.tbz" 
 [ -f "$CONFIGS" ] || CONFIGS="/cdrom/KNOPPIX/configs.tbz" 
 [ -f "$CONFIGS" ] || CONFIGS="/mnt/floppy/configs.tbz" 
 if [ -f "$CONFIGS" ]; then 
 echo "Extracting config archive $CONFIGS..." 
 tar -jpPtf "$CONFIGS" | while read i; do rm -f "$i"; done 
 tar -jpPxf "$CONFIGS" ; chown -R knoppix.knoppix /home/knoppix 
 fi 
 mount >/tmp/mount.txt 
 
 So, when the configuration is loaded you can see that the home dir is mounted 
correctly. 
 
 knoppix@ttyp0[knoppix]$ cat /tmp/mount.txt 
 /dev/root on / type ext2 (rw) 
 /dev/cdrom on /cdrom type iso9660 (ro) 
 /dev/cloop on /KNOPPIX type iso9660 (ro) 
 /ramdisk on /ramdisk type tmpfs (rw,size=817824k) 
 usb on /proc/bus/usb type usbdevfs (rw,devmode=0666) 
 /dev/sdb1 on /mnt/sdb1 type ext2 (rw,nosuid,nodev) 
 /mnt/sdb1 on /home/knoppix type none (rw,bind) 
 
 However, afterward it is unmounted for some strange reason. 
 
 knoppix@ttyp0[knoppix]$ mount 
 /dev/root on / type ext2 (rw) 
 /dev/cdrom on /cdrom type iso9660 (ro) 
 /dev/cloop on /KNOPPIX type iso9660 (ro) 
 /ramdisk on /ramdisk type tmpfs (rw,size=817824k) 
 usb on /proc/bus/usb type usbdevfs (rw,devmode=0666) 
 /dev/sdb1 on /mnt/sdb1 type ext2 (rw,nosuid,nodev) 
 automount(pid592) on /mnt/auto type autofs 
(rw,fd=4,pgrp=592,minproto=2,maxproto=4) 
 
 I think this can be fixed by adding a few lines to 
/etc/rcS.d/S00knoppix-autoconfig Line 1058 
 Currently: 
 umount "$MYCONFMOUNTPOINT" 2>/dev/null 
 Suggestion: 
 Add a check to see if $MYCONFMOUNTPOINT is mounted as home. 
(diff file below)
 
 Thanks,

PS. I added a couple lines to copy the skel files to /home/knoppix when you 
don't load a persistent home directory.


1009,1011d1008
< else
< #if home not mounted from anywhere, then copy the skel files over.
< cp -r /etc/skel/* /home/knoppix
1060,1061d1056
< #echo "HomeDevice: $MYHOMEDEVICE ConfDevice: $MYCONFDEVICE HomeMount: 
$MYHOMEMOUNTPOINT"
< if [[ "$MYHOMEDEVICE" != "$MYCONFDEVICE" && "$MYHOMEMOUNTPOINT" != 
"$MYCONFDEVICE" ]]; then

< fi
